Abstract: In the course of continuous movement along a track that is essentially circular, articles undergoing an imprinting process are arranged with their longitudinal axes vertical and passed through a plurality of print stations, individual silk screen stencils at the stations being adjusted to the resulting changes in the position of the article that occur during the imprinting process as the article moves through the printing machine. The silk screen stencils are pivoted for maintaining the line of contact of the silk screen stencils with the article being printed upon on a radius of the circular track through the article being printed upon during movement of the article along the circular track.

Abstract: In the course of continuous movement along a track that is essentially circular, articles undergoing an imprinting process are passed through a plurality of print stations, individual silk screen stencils at the stations being adjusted to the resulting changes in the position of the article that occur during the imprinting process as the article moves through the printing machine. The articles can be arranged with their longitudinal axes either horizontal or vertical during the imprinting process. It is also possible to introduce the articles into the machine with their longitudinal axes vertical, then move them into a position in which their longitudinal axes are horizontal and imprint them in such a position, and then bring the imprinted articles once again into a position in which their longitudinal axes are vertical so that they leave the machine in this position.
